Application March 24, 1934, Serial No. 717,193

1 Claim.

My invention has reference to floor drains, and has for its purpose to increase the utility and efiiciency of such devices. The chief object thereof is to provide a seal for the mouth of a 5 drain, so that all unsanitary and unhealthy conditions surrounding devices of that kind which are now in use will be done away with.. By this means it will be possible to effectively interfere with the return of back water or sewage through the drain, and with the escape of noxious fumes and odors from the drain. The drain and its immediate locality will also cease to be a place for harboring all kinds of vermin, and their passage into or out of the drain.

In many cities the sewer systems are inadequate to dispose of the water, especially at the time of heavy storms, as a result of which backwater and filth finds its way into the basements, flooding them, and causing conditions of wet and damp over long periods of time. By means of the invention this can be eflectively prevented. This is done by means of a positive closure for the mouth of the drain, with the closure locked in place so that it can not be accidentally dislodged. It is also provided with means for ren dering the same leak proof for liquids or gases. The closing plate and means for securing the same in place are flush with the floor, so as to form no obstacle therein.

Another purpose of the invention is to do away with the use of back-water gates, ball-valves, and traps of various kinds. Neither does it contain any screens or pockets now commonly found in drains, and which frequently interfere with the successful operation thereof by collecting quantities of sweepings, lint, slush, and other accumulations.

The invention is of simple construction, and can be cheaply produced without special machining of any of the parts.

The above-named, and other features and advantages of the invention will more fully appear from the following specification, taken in connection with the accompanying drawing, in which;

Fig. 1 is a medial vertical section through a floor drain equipped with the invention.

Fig. 2 is a perspective view thereof, with the cover 8 in elevated position.

The reference number I indicates a basin of circular form, of the type which are generally installed in the floors of basements, garages, and the like. Said basin is fitted at its upper edge with a flange 2, projected at opposite sides into extensions 3 and 4. In the extension 4 is a recess 5, in which is fixed a pin 6, engaged by a hook member I on the edge of a circular plate 8, which forms a cover for the basin I. The hook and pin form a hinge connection, permitting the plate 8 to be raised, and entirely removed from the drain.

At the opposite side of the plate 8 is a lip 9, for engagement by a catch I0 in a recess II in the extension 3, and held pivotally in place by a pin l2 fixed in the extension. The flange 2 is fitted with an annular seat I3, for the support of the plate 8, and interposed between the plate and said seat is a rubber ring I4 of rounded form, held in a groove in the lower face of the plate. The lower face of the catch I0 is beveled for engagement with the downwardly inclined lip 9, and such engagement tends to clamp the plate 8 tightly in place, with a compressive force on the ring I4, with a tendency to flatten the ring against the face I3, thus forming an impervious seal between the ring and seat, as well as between the ring and plate 8.

In the body of the basin I is an annular seat I5, on which is supported a grating I6, straining out larger objects at such time as the drain is in use, with the plate 8 raised or entirely removed. When the plate is removed it is possible to sweep water into the drain from any direction without interference.

In the lower part of the basin I is an opening to receive a cylindrical member I1, projected above the floor of the basin to prevent sediment from entering the same, and also fitted in its lower end with a seat for a ball valve I8, located in the connection I9 below the basin, and which valves are in common use. In the event of the cover 8 being accidentally left open the ball valve would provide a secondary safeguard, to prevent the entrance of back-water into the basin.

When the cover 8 is open the grating I8 can be removed from its seat, to get at parts below the same, and it can be quickly fitted in place when the drain is being installed.

It will be apparent that when the cover is securely closed not only will it form a barrier to cock-roaches, and other kinds of bugs and vermin, but it will successfully block any attempt of water or sewage to work back through the drain, as well as to form a seal against the passage of gases and fumes from the sewer.

While the basin and cover have been set forth herein as of a circular formation, they are not limited to such shape, and changes can be made in the form and arrangement of parts without departing from the spirit of the invention. What I claim, and desire to secure, is;- A floor drain, comprising a. basin provided with an outlet and having an annular seat at its upper edge, a cover hingedly and removably connected at one side of said seat and adapted for support thereon, a catch pivoted at the opposite side of said seat having an inclined face engageable with an oppositely inclined edge of said cover, and a sealing element interposed between said cover and seat, and compressible by the wedge engagement of said catch and cover.
